PUNCH-BLOCK FOR HEADING-MACHINES.

Specification of Letters Patent.

Patented Dec. 19, 1911.

To all whom it may concern:

Be it known that I, ERNEST W. DUSTON, a citizen of the United States, residing at \Vaterbury, county of New Haven, State of Connecticut, have invented an Improvement in Punch-Blocks for Heading-Machines, of which the following is a specification.

This invention relates to machines for making bolts, screws and the like and has reference more particularly to machines for forming the heads of such articles.

The general object of the invention is to provide a machine having means whereby the punches, which are employed to upset and form the heads on the bolts, may. be adjusted upon the punch carrier so as to bring the same into proper position and alinement.

The more particular objects of the invention, together with means whereby the same may be carried into effect, will best be understood from the following description of one form or embodiment thereof illustrated in the accompanying drawings forming a. part i of this specification.

In said drawings, Figure 1 is a front elevation of the punch head of a bolt heading machine, showing the punch carrier, punch blocks, and punches; Fig. 2 is a side elevation, partly in vertical section, of the parts shown in Fig. 1; Fig. 3 is'a front elevation and Fig. 4 a plan view of one of the slides which carry the punch block.

12 denotes a punch head which is slidably mounted in suitable guides in the machine frame and is operated by suitable mechanism (not shown) to advance and'retract the punches.

13 denotes a punch carrier which is slidably mounted in the punch head 12 and is operated by suitable mechanism (not shown) to shift the punches on the head 12 to bring any desired punch into operative position with respect to the die which holds the blank on which the head is to'b'e formed. This die, the mechanism for actuating the unch head, and the mechanism for operatmg or shifting the punch carrier are not shown herein as they form no part of the present invention and are familiar to those skilled in the art.

14 denotes punch blocks carrying heading punches 15, said punches being preferably detachable from the punch blocks and secured in place therein by suitable means, such as screws 16. In accordance with the present invention the punch blocks 14 are mounted on the punch carrier 13 for independent adjustment both longitudinally and laterally of the said punch carrier.

17 denotes slots in the punch carrier 13 in which are located slides 18, said slides being preferably formed with ribs 19 received in rabbets formed in the punch carrier adjacent the slots 17. The slides 18 are guided in the slots 17 and are movable therein longitudinally of the punch carrier 13 by means of adjusting screws 20, preferably in threaded engagement with the punch carrier 13 and rotatably connected with the slides 18 by means of pins 21 which engage grooves in the ends of said screws.

The slides 18 are formed with recesses 22 to receive bosses 23 formed on the punch blocks 14, said punch blocks being further pivotally secured to the slides 18 by means of bolts or screws 24. The punch blocks 14 are movable about their pivots to provide an adjustment transverse to the punch carrier 13." To efi'ect this adjustment and hold the punch blocks in adjusted position the following means are provided.

25 denotes studs or lugs projecting from the punch carrier 13 and loosely received in recesses '26Tformed in the punch blocks 14. Said punch blocks are provided at either side of the recesses 26 with adjusting screws 27 on aging at their ends the studs 01' lugs 25: 'will be seen by proper manipulation of the adjusting screws 27 the punch block's'l may be swung about their pivots irrespective of the positions of the slides 18, said screws 27 also acting to secure 'said punch blocks in adjusted position.

The slides 18 provide means whereby the punch blocks may be independently adjusted in a rectilinear direction longitudinally of the unch carrier 13, while the pivotal mounting of these blocks permits them to be independently adjusted transversely of said punch carrier. By virtue of these independent adjustments either or any punch block may be brought into proper position and alinement with respect to the die without afiecting the adjusted osition of the other punch block or blocks. Having thus described my invention, I claim:

1. The combination with a punch carrier, of a plurality of punch blocks provided with heading punches mounted on said carrier and independently adjustable thereon.

2. The combination with a punch carrier, of a plurality of punch blocks provided with heading punches mounted on said carrier, said punch blocks being independently adjustable longitudinally of'said carrier.

3. The combination with a punch carrier, of a plurality of punch blocks provided with heading punches mounted on said carrier, said punch blocks being independently adjustable transversely of said carrier.
